Knowledge regarding the characteristics of soils in Bogotá basin has been possible to get through previous microzonation studies. However, there is still insufficient knowledge of the crustal velocity structure of the region. Bogotá is located in a region prone to a significant seismic hazard. Histo...

description Knowledge regarding the characteristics of soils in Bogotá basin has been possible to get through previous microzonation studies. However, there is still insufficient knowledge of the crustal velocity structure of the region. Bogotá is located in a region prone to a significant seismic hazard. Historically, the city has been affected by strong earthquakes, reaching moment magnitudes greater than or equal to 7. Furthermore, the city was built on a lacustrine basin, with soft soils of considerable depth that may strongly amplify the ground motion during an earthquake. In this article, we describe the development of a first crustal structure and material properties model for the region of Bogotá, Colombia, covering an area of about 130 km by 102 km. This effort aims at constructing a realistic 3D seismic velocity model using geological and geotechnical information from several sources. Major geological units have been identified and mapped into the model. The Inverse Distance Weighted (IDW) interpolation was used to create continuous surfaces delimiting the geological units. Seismic-wave properties are assigned to any point in the domain using a location-based approach. We expect this model to be useful for a wide range of applications, including dynamic ground motion simulations and fault system modeling.

Sin embargo, todavía hay un conocimiento deficiente sobre las velocidades de onda y densidades de los suelos en la región. Bogotá está localizada en una región propensa a una amenaza sísmica significativa. Históricamente, la ciudad ha sido afectada por terremotos fuertes, alcanzando magnitudes de momento mayores o iguales a 7. Además, la ciudad se construyó sobre una cuenca lacustre, compuesta por suelos blandos de considerable profundidad, los cuales pueden amplificar considerablemente el movimiento durante la ocurrencia de terremotos. En este artículo presentamos el desarrollo de un primer modelo de material para la ciudad de Bogotá y municipios cercanos. Este esfuerzo tiene como objetivo construir un modelo sísmico de velocidades utilizando información geológica y geotécnica proveniente de varias fuentes de información. Un conjunto amplio de estructuras geológicas fue identificado e incluido en el modelo. Las superficies continuas que delimitan las estructuras geológicas fueron creadas interpolando mediante la distancia inversa ponderada (IDW) entre cortes geológicos disponibles. Las propiedades de las ondas sísmicas son asignadas por medio de un enfoque basado en la localización del punto de interés. Se espera que este modelo sea útil para una amplia gama de aplicaciones, incluyendo simulaciones dinámicas de movimientos de tierra y modelamiento de sistemas de fallas.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/64097Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónRiaño, Andrea C. and Reyes, Juan C. and Yamin, Luis E. and Montejo, Julian S. and Bustamante, Jose L. and Bielak, Jacobo and Pulido, Nelson and Molano, Carlos E. and Huguett, Alcides (2017) Development of a first 3D crustal velocity model for the region of Bogotá, Colombia.
